[PATCH 02/11] staging: rtl8188eu: ctrl vendor req value is always 0x05

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



The bRequest value for the vendor specific control requests sent by this
driver is always 0x05. Replace the function parameter with a define. Use
the same define as the rtlwifi driver.
